PAPER-BAG SPECIFICATION forming part of Letters Application filedNovember 11, 1878.

MACHINE.

Patent No. 226,287, dated April 6, 1880.

Patented in England, July'Qd, 1878.

To all whom it may concern:

Be it known that I, ERNEST DANGOISE, of Brussels, Belgium, have inventedcertain Improvements in Paper-Bag Machines, for which I have obtainedBritish Letters Patent No. 2,896, dated July 20, 1878, sealed October 8,1878, and of which the following is a specification.

The object of my invention is to construct a machine for automaticallymaking paper bags from two strips of paper, the overlapping edges of onestrip being first pasted and folded over the other strip, and atransverse line of paste applied to one strip at the point where thebottom of the bag is to be formed, the pasted tube thus formed beingafterward cut to the required length by severing the tube close to thesaid transverse line of paste, the closed end being also pasted andfolded over to strengthen the bottom of the bag.

A further object of my invention is to combine with the parts of themachine for making the bags devices for 'printi n g the bags before theyare cut in to lengths and counting them before they are delivered fromthe machine in a complete form, a still further object being to adaptthe machine to the making of wrappers, labels, and similar articles.

These objects I attain in the manner which I will now proceed todescribe, reference being had to the accompanying drawings, in which'Figure 1, Sheet 1, is a side view of my improved machine for making andprinting paper bags; Fig. 2, Sheet 2, a plan view of the same; Fig. 3,Sheet 3, a longitudinal vertical section, drawn to an enlarged scale, ofone end of the machine 5 Fig. 4, Sheet 4, a corresponding section of theother half of the machine; Fig. 5, Sheet 5, a transverse section on theline a 1), Fig.1, drawn to the same scale as Figs. 3 and 4; Fig. 6,Sheet 6, a similar section on the line a (I, Fig. 1, Figs. 7 and 8,Sheet 7, a side view and plan view, respect ively, of the devices forcutting, folding, and pasting the bottom of the bag; Figs. 9,10, and 11,a reverse side view, a plan view, and detached sectional view,respectively, of the devices for folding and pasting the overlappingedges ot' one strip onto the other; Figs. 7 12, 13, and 14, viewsshowing the successive steps taken in making the bag; Figs. 15, 16, 17,and 18, Sheet 8, views of modifications of parts of the machine.

By this machine a number of bags may be made simultaneously, the numberbeing limited only by the relative size of the bags and width of themachine.

A machine two feet two inches in width between the side frames iscapable of making four bags five inches in width at one operation, ormore than seven thousand per hour, the bags being completely andautomatically finished, printed, and delivered in counted packages orpiles at one end of the machine.

Any size of bag may be made on this machine, and if necessary differentsizes of bags maybe made at the same time by a proper adjustment of thefolding, pasting, and printing devices.

The machine in the accompanying drawin is shown as arranged for makingfour bags at a time.

In order that the construction and opera tion of the machine may be morereadily understood, I will first describe the method of making the bag.reference being had to Figs. 12, 13, and 14.

Each bag is made from two strips of paper, a and f, Fig. 12, deliveredin endless sheets from suitable rolls, the sheet f(the upper one in themachine) being slightly wider than the sheet 6, so that its edgesoverlap the edges of the latter. As the paper is fed through the machinethe upper sheet,f, receives a transverse line, g, of paste or gum atintervals equal to the length of the bag, and the overlapping edges f fare then partially folded down, as shown in Fig. 13, and gum or pasteapplied to the inner faces of the folds, which are then completelyfolded down on the strip c, Fig. 14. The pasted tube thus formed is thensevered first in front of the line of gum or paste g, the closed end ofthe partiallyfinished bag having been bent and pasted or gummed, so asto form a strengthening-fold, h, on the bottom of the bag, Fig. 14,which is then complete, it having been printed before being cut.

I will now proceed to describe my improved machine for making bags inthe manner described.

A is the base of the machine, and B, B,

B and B the frame supporting the operating parts. The portion B of theframe carries the rolls of paper, the devices for pasting the sheetstransversely, the devices for cutting the corners of the strips to formthe bags, and the curved recess i, Fig. 13, in that portion of eachlower sheet which is to form one of the edges of the open end of thebag, and also the devices for pasting and folding the overlapping edgesof the upper sheets.

The portion B of the frame carries the endless apron and reciprocatinggriping-jaws for transferring or feeding the paper from the pasting andfolding devices to the printing mechanism, which is, carried by theportion B of the frame.

The portion 13 of the frame carries the de vices for cutting the pastedand printed tubes into bags and for pasting and folding the closed endof the bag, and also the devices for counting and delivering thefinished bags, Figs. 1 and 2.

The operating parts of the machine are driven from the shaft 0, providedwith a fly-wheel, D, Figs. 1, 2, and 4, and fast and loose pulleys, Fig.5. On this shaft G are two gear-wheels, E E, on opposite sides of theframe, and gearing with wheels F F on a transverse shaft, Gr, Figs. 1,2, 4, and 5.

The printing mechanism is operated from this shaft G by deviceshereinafter described, and the griping-jaws L, for feeding the pastedtubes, have a reciprocating motion imparted to them from the same shaftG through the medium of a longitudinal shaft, 0, and bevelgearing, asillustrated in Figs. 2, 5, and 6, this shaft 0 deriving its motion fromthe drivingshaft 0 through the medium of the gear-wheels Q, Q, Figs. 1and 4, and the bevel wheels P 1?, Figs. 2 and 5.

1 will now proceed to particularly describe the details of constructionof the machine, and, for the sake of clearness, will describe the partsin their order, beginning at that part of the machine where the sheetsof paper are first acted on in the operation of making the bag.

Referring to Figs. 1, 2, and 3, the rolls of paper from which the bagsare to be made are mounted on twohorizontal shafts, 104 and 105, therebeing in the present instance four bobbins or rolls of paper on eachshaft, and the paper being preferably drawn off from the upper and undersides, alternately, of the rolls on each shaft, as shown in Figs. 2 and3. For the manufacture of bags five inches wide the rolls of paper onthe upper shaft are each five and three-fourths inches in width, whilethe lower rolls are each five inches in width. A slight tension may beimparted to each roll by means of pivoted pressure-pads, as shown in thedrawings. The bands or sheets of paper from the upper shaft, 104, passover a horizontal bar, 106, and thence under a similar bar, 107, mountedin theopposite side frames. These sheets then pass below a metal strip,30, Fig. 3, held freely in guides in the frame, and

below this strip is a tank or trough, 23, containing gum, paste, or anysuitable adhesive substance. On the upper edges of this trough ismounted an axle, 24, and on opposite ends of the shaft, within thetrough, are two arms, 2' 28, Figs. 2 and 3, to which is secured atransverse strip, 29, the latter, when raised, being immediately beneaththe strip 30, as shown in Fig. 3. On the end of the axle 24 is a piniongearing into a rack on an arm, 25, Figs. 1, 2, 3, and 9, under thecontrol of a cam, 26, on the axis 14, which receives a rotary motionfrom the longitudinal shaft 0 through the bevel-gear 15 16, Fig. 2. Thiscam 26 imparts to the axle 24 through the medium of the rack and pinion,a vibratory motion of about a quarter of a revolution, so that the strip29 will alternately dip into the paste in the trough and come intocontact with the under side of the sheets of paper to impart to theunder side thereof, at the proper intervals as the paper is fed forward,transverse lines of paste necessary to close the bottom of each bag. Onthe said shaft 14 are two sets of cams, 21 and 22, Fig. 3, which imparta reciprocating n10- tion to bars'or rods 20, carrying cheek-pieces, inwhich is adj ustably secured the transverse bar 19, holding thecutting-punches 17. These reciprocating punches act, in connection withthe stationary die 18, secured to the frame, to cut from the bands ofpaper (which pass from the lower set of rolls over and under the bars108 and 109 to the drums 110) the half-moons or recesses i, Fig. 13, andthe notches j, to facilitate the subsequent folding of the corners ofthe bag.

The corresponding bands of paper from the two sets of rolls meet inpassing over drums 110, immediately above and between which are thelongitudinal folding-bars 35 36, the outer ends of the latter being inthe form of inverted plowshares, Figs. 2, 3, and 10, for folding theoverlapping edges of the upper sheets of paper to a right angle, asillustrated in Fig. 13. These bars 35 36 are secured by set-screws toslotted transverse bars, as shown in Figs. 3 and 10, so that thefolding-bars may be adjusted laterally to various widths of bags. Thesefolding-bars are arranged to pass between the flanges of grooved pulleys33, secured to the axle 32, Figs. 3, 10, and 11, which is mounted inbearings in the side frames immediately over a trough, 31, forcontaining paste, gum, or other suitable adhesive substance. In thebottom of this trough is arranged a rotary brush, 34, for distributingthe paste evenly over the flanges of the pulleys, so that as each bandof paper passes over the adjoining flanges of adjoining pulleys, asindicated by dotted lines in Fig. 11, the inner faces of the flaps orfolds fj", Fig. 13, will receive continuous lines of paste or gum priorto being folded down onto the other sheet of paper by the plowshares 35,Figs. 3 and 10.

On the adjacent ends of the shaft 32 and the shaft of the rotary brushare toothed wheels, which gear into each other, so that the two shaftswill rotate in opposite directions, and thus'insure the evendistribution of the paste over the flanges of the pulleys. Anintermittently-rotatin g motion is imparted to these shafts by thefollowing devices: At-

tached to the reciprocating griping-jaws L, for

feeding the paper at one side of the frame, is arack, 38, guided by ananti-friction roller, 38, Figs. 1, 3, 9, and 10. This rack gears with apinion, 39, Figs. 9 and 10, which turns loosely on the center pin, 40,Fig. 9, and attached to this pinion is an arm carrying a spring-pawl,43, which engages with a ratchetwheel, 41, Figs. 9 and 10, secured to atoothed wheel, 42, also mounted loosely on the'pin 40. This wheel 42gears with the toothed wheel 32 on the shaft 32, so thatin the backwardmovement of the feeding-jaws L the rack 38 will move the pulley 39, butthe spring-pawl 43 will slide over the teeth of the ratchet-wheel 41,and the wheels of the shafts 32 and 34 will not be moved; but on theforward movement of the jaws L the rack 38 willcause the springpawl toengage with the teeth of the ratchet, and so impart motion to thepasting pulleys and brush.

From the folding-bars 35 36 the sheets of paper, which have now beenmade into the form of pasted tubes, now pass under the roller 37, Fig.3, and to the feeding mechanism for transferring the paper tubes to theprinting .mechanism. This feeding mechanism consists of griping-jaws L,between which passes an endless band, 54, passing also over the rollers55 and 57 and the adjustable roller I 56, Figs. 3 and 4. These jawsconsist of a lower plain plate, 52, adapted to slide longitudinally ofthe machine on guides and 51, forming part of the side frames, Figs. 1,2, and 3. The opposite ends of this plate are provided with verticalstandards, between which is guided the movable plate 52, and to theunder face of the latter is secured, by bolts and thumb-nuts, the steelface-plate 53, pressuresprings being interposed between theplate 52 andface-plate The paper, together with the endless apron 54, is gripedbetween the plate 52 and spring-plate 53 on each forward movement ofthese feeding plates or jaws L, the face of the plate 53 having groovesrunning diagonally in opposite directions, in order to obtain a firmgripe on the paper.

As I have already said, these jaws have a reciprocating sliding motionimparted to them on the guides 50 51 by means of the connecting-rods KK, secured to the crank-pins J, which can be adjusted in radial slots inthe wheels F F, Fig. 1. so as to vary the length of the movement of thejaws on their guides in accordance with the length of the bag to bemade. On the opposite ends of the plate 52 are anti-friction rollersembracing bars 140 141, Figs. 1, 2, 3, and 4, carried byverticallyguided rods 142, 143, 144, and 145, acted on, respectively, bycams M, M, l and M. The two shafts carrying these cams receive a rpta-rymotion from the shaft 0 through the medium of the bevel wheels N N, Fig.2. The operation of these cams is so timed that on the backward motionof the feedingjaws L the bars 140 141 will be caused to keep the plates52 53 open or separated; but when the jaws are about to move forward theupper plates 52 53 are caused to descend and gripe the paper and apronand carry both with them to the end of their forward movement.

Immediately over the roller 55 .is a spring presser-bar, 45, and thereis a similar spring presser bar, 44, immediately over the roller 57, thesaid bars being carried by vertically-guided rods on opposite sides ofthe frame of the machine. These vertical rods are so acted 011 by cams46 48 and 47 49, Figs. 1 and 2, as to depress the said presser-bars downupon the rollers toretain the paper and apron during the return orbackward movement of the feeding-jaws L, and to raise the presser-bars,so as to release the paper and apron when the latter are fed forward onthe forward movement of thejaws L, Fig. 3.

The bearings of the roller 56 are controlled by a vertical screw, 58,and a horizontal screw, 59, to permit the tension of the apron 54 to bevaried as occasion may require, Fig. 3.

From the above;descrihed feeding or transferring devices the tubes ofpaper pass to the printing mechanism carried by the portion B of theframe,96 being the stationary bed-plate, covered with asuitable blanket,over which the tubes of paper pass to receive an impression from thetype or other printing-surface carried by the movable plate i, Fig. 4.This printing-plate I is guided at opposite ends in vertical standards60 61, Figs. 1, 2, and 4, and a vertically-reciprocating motion isimparted to the printing-plate by means of cams H H on the transverseshaft G acting on vertical rods 1, secured to opposite ends of the saidplate I, and having extensions surrounded by spiral springsacting in anupward direction on said vertical rods, as indicated in Figs. 1 and 5.

The devices for inking the printing-surface may be of any ordinaryconstruction, and consist, essentially, in the present instance, ofink-receptacles 62 and 63, inking-rollers 72, 73, 77, and 7S, andinking-plates 75 and 76. These several devices are constructed andoperated in the following manner: The inkreceptacles 62 and 63 aremounted on the side frames on opposite sides of the printing-plate I,and the receptacle 62 is provided with a roller, 68, while thereceptacle 63 is provided with a similar roller, 69, Fig. 4, and on oneend of each roller is a ratchetwheel, acted on, one by a weighted pawl,7 0, carried by an arm, 64, and the other by a similar pawl, 71, carriedby an arm, 67. (See Figs. 1,2, and 5.)

These arms 64 and 67 are connected by links and bell-crank levers 65 and66 to the plate I, as indicated in Fig.1 and by dotted lines in Fig. 4,so that when the machine is in operation the vertically-reciprocatingmotion of said plate will ,impart to the rollers 68 and 69 anintermittent rotary motion through the said links, pawls, and ratchets.In horizontal guides in the side frames, immediately below theink-receptacles, Fig. 5, is arranged to slide the roller-carriage 74,carrying the four inkrollers 72 73 and 77 78, Fig. 4, the roller 74being to transfer the ink from the roller 68 to the inking-plate 75, andthe roller 73 being to transfer the ink from the roller 69 to theinking-plate 76 and spread it thereon at each reciprocating movement ofthe carriage, while the rollers 77 and 78 transfer the ink from theplates and 76 to the printing-surface. The carriage 7 at is provided onthe two sides of the frame with racks gearing with two toothed wheels,79, Figs. 4 and 5, on a shaft carrying pinions 80, gearing with toothedsectors 81, secured to a shaft carrying toothed sectors 82, which areacted on by racks 83. These racks 83 are under the control of cams 84;on the shaft 85, which receives a rotary motion from the shaft G throughthe medium of the gear-wheels 86 87, Fig. 4, so as to impart through thesaid gearing the necessary horizontal reciprocating motion to thesliding carriage 74.

Each inking-plate 75 76 is mounted on an adjustable central pivot, 8889, to permit each of the said plates to have a slight turning oroscillating motion on its center, so that the ink may be spread evenlyover the plates, and the motion of the two plates is made simultaneousby connecting them at one side by a rod, 91, as indicated in the planView, Fig. 2. The oscillating or turning motion is imparted to the saidplates through the arm 90, which is connected to a pin on the edge ofthe plate 75, the other end of the arm being provided with a toothedsector in gear with the rack 92, controlled by cams 93 on a shaft whichreceives a rotary motion from the shaft through the gear-wheel 95 andpinion 94, the latter being shown by dotted lines in Fig. 4.

From the above-described printing mechanism the tubes of paper pass tothefeed-rolls 97 98, which present them to the devices for cutting thesaid tubes into lengths and for folding and pasting the closed end. ofthe partly-finished bag.

In standards 99, forming part of the oppo site side frames, is guidedthe transverse plate carrying the cutting-knife R, to the ends of whichare connected the vertical rods :t B, Fig. 6, acted on by the cams U Uon the shaft T. This shaft T is driven from the longitudinal shaft 0through the medium of the bevel-gear S S, Figs. 2 and 6, and by thismeans a vertically-reciprocating motion is imparted to the knife R,which acts, in connection with a corresponding transverse steel edge, tocut the paper tubes immediately in front of the lines g of paste, Figs.12, 13, and 14.. To

the rear ofthe knife-plate is attached a weighted bar, 139, by means ofbolts 139, passing freely through eyes on the said plate, so that whenthe knife descends the bar will rest on the paper on a suitably-arrangedbed, as shown in Fig. 7, and hold the paper in position, while the knifecontinues its descent and severs the paper tubes into the properlengths. At the 70 same time a strip, 100, fixed to the back of theknife, descends on the pasted edges of the advancing tubes and bends theedges h to a right angle, Fig. 14;, over the edge of the above-mentionedbed; and to the angle of the 75 fold thus formed paste or gum is appliedby means of the vibrating blade W, the axle of which is mounted inhearings on the upper edges of the paste-trough 111, Fig. 7.

The necessary vibrating action is imparted to the blade to cause it todip into the paste, and then into contact with the folds on the ends ofthe paper tubes, by means of a rack, X, gearing into a pinion on the endof the axle of the blade, this rack being operated by a cam, V, on therotating shaft T, Figs. 6 and 4.

After each set of bags is severed from the tubes the latter are fedforward by a thin straight blade, 101, by the following means: The blade1.01 is kept straightby being stretched in a frame with a tighteningscrew-bolt, 102, like a buck-saw frame, Figs. 4 and S. This frame isarranged to slide in guides in the side frame, and is provided on itsunder side with two racks, 130, Fig. 4, which gear with pinions 128 and129, both secured to the same shaft, Fig. 8. To the end of the saidframe is pivoted a transverse shaft, 119, Fig. 8, carrying at' oppositeends arms 120, which are provided with anti-friction rollers adapted torun on inclined planes 123 and 124 on the side frames of the machine.

To the reciprocating feeding-jaws L are secured, on opposite sides ofthe frame of the machine, two longitudinal bars, 12 and 11S, Figs. 1, 2,4, 7, and 8, which are provided with adjustable stops 121 and 122,adapted to come into contact with projections on the arms 120, as shownin Figs. 7 and 8, so that as the said jaws L and bars 12 and 118 advancein their forward movement the latter, through the medium of the saidstops and arms, push the frame and blade 101 forward, and with them thetubes of paper between the feed-rolls 5 and 6; but as the frame advancesthe antifriction rollers on the arms 120 travel up the inclined planes123 124, and the projections on the said arms are thus released fromcontact with the stops 121 122, so that the forward movement of theframe ceases. A projecting pin, 125, on the advancing bar 118 then comesinto contact with an arm of the toothed sector 126, Fig. 7, gearing intoa pinion, 127, on the shaft carrying the pinions 128 129, so that the 125 latter, acting on the racks 130, Fig. 4, cause the return of the framewith the blade 101 to its normal position.

An intermittent motion is imparted to the lower feed roll, 98, by meansof devices sub- 1 o stantially similar to those by which motion isimparted to the shaft 32, carrying the pulleys 33. On opposite ends ofthe shaft. of the roll 98 are pinions 131, Fig. 7, turning freely onsaid shaft and in gear with racks on the under side of thelongitudinalbars 12 118. To each of these pinions 13L is attached a spring-pawl,132, adapted to act on two ratchet-wheels, 133 134, Figs. 7 and S,secured to the shaft of the roll 98. so that on the forward movement ofthe bars 12 118 the said gearing and pawls and ratchets cause thefeed-roll 98 to rotate; but on the return movement of the said bars thepawls slip over the ratchet-teeth and the rolls remain stationary, theshaft of the roll being acted on by a suitable friction-brake at themoment when the roll ceases to revolve.

The pressure and feed rolls 1, 2, 3, 4, 5, and

6 are provided with a number of copper-wire rings let into groovestherein, as indicated in Fig. 8, the said rolls receiving a uniformintermittent motion through the train of wheels 103, geared with thefeed-roll 98 through the pinion 135. These rollers conduct the completedbags to and deposit them in piles upon the endless band 7.

The following are the devices for automatically counting the completedbags and arranging them in piles: On the rotating shaft T is aneccentric, Y, and arm y, Figs. 4 and 6, connected to an arm pivoted tothe shaft 8, and carrying a pawl engaging with the teeth of theratchet-wheel Z, which is keyed to the said shaft 8. To this shaft isalso secured a wheel 9, provided with a notch in its edge, into which isadapted to fall a projection on an arm, 10, pivoted to the axle of theroller 13, as indicated by dotted lines in Fig. 4.. The outer end ofthis arm 10 carries a pinion, 11, which gears with a pinion on theroller 13, and which, on the depression of the said arm 10, is raisedinto gear with a rack on the abovementioned bar 12.

The wheel Z is provided, in the present instance, with twenty fiveteeth, and consequently there will be twenty-five revolutions of theshaft T, and the same number of completed bags deposited in each pile onthe apron 7 at each complete revolution of the wheel 9. At the momentwhen the shaft 8 completes its revolution the projection on the arm 10falls into the corresponding notch in the wheel 9, and the pinion 11 isthereby brought into gear with the rack on the bar 12, and this bar,being then on its return or backward movement will cause the roller 13,through the medium of said pinion, to revolve, and the apron 7,consequently,to advance with the piles of bags a distance slightlygreater than the length of the bags.

The operation of the machine will be readily understood from thepreceding description, so that it will suffice now to summarize theprincipal steps of the operation.

The bands of paper--four in the present insta11ce-from the upper rolls,104, after passing under and over the bars 106 and 107, receive.transverse lines of paste at the proper intervals to close the bottom ofthe bag from the vibrating paster 29, Fig. 3. These bands then pass tothe drums 110, where they unite with a corresponding number of narrowerbands of paper from the lower rolls,'105, these bands having beennotched and partially cut by the cutters 7o 17. The overlapping edges ofthe upper bands are then bent down over the lower bands by the bars 3536, and these folds or flaps receive on the'inside edges a continuousline of paste from the pulleys 33. The pasted folds or flaps are thencompletely folded over onto the lower bands of paper by the devices 35on the end of the folding-bars, Figs. 3 and 10. The pasted endless papertubes thus formed are then transferred by the feedingjaws L to theprinting mechanism, Fig. 4, where they receive the desired printedimpression. They then pass to the cutting-knife R, which severs theminto lengths, and at the same time the closed ends of the advancingtubes are folded and pasted to form the bottoms of the bags. Thecompleted bags then pass to the pressure and guide-rolls 1 23, Ste,which deliver them onto the apron 7 where they are automatically countedand arranged in piles or packages.

In order that the action of the folder and paster W may coincide withthat of the paster 29 in forming the bottoms of the bags, the portion Bof the frame is arranged to .be adjusted longitudinally on the base A,and for this purpose is provided with pinions 114, gearing with racks115 on the said base, Figs. 1 and 3, the shaft carrying the 'saidpinions being operated by a worm, 112, gearing with a worm-wheel, 113,on said shaft.

The portion B of the frame may also be adjusted on the base in a similarmanner, the said portion of the frame being provided with pinions 116,gearing with racks 117 on the base, as shown in Figs. 1 and 6, to permitthis adjustment.

The length of the paper bags may be varied by proper adjustment of thecrank-pinions J J in the radial slots of the wheels F F, so as to varythe length of movement of the feedingjaws L and bars 38, 12, and 118.

The above-described machine may be adapted 'for the manufacture ofgummed and printed address-wrappers by dispensing with the pastingdevices 29 and W, which apply the transverse lines of paste, and by soarranging the knife It that it shall cut the paper without folding it,as indicated in Figs. 15 and 16, Sheet 8. In such case, also, the rolls1, 2, 3, 1, 5, and 6 are dispensed with. and the apron 7 brought closeup under the knife. The apron in this case passes over a roller, 146,driven by an endless chain, 147, from the roller 13.

If desired, the use of the printing mechanism and the cutting devices 17may be dispensed with.

Some features of this machine may also be employed for the making ofsuch articles as printed labels, tickets, 85c. For this purpose 1 0 thenumber of rolls of paper on the axles 104 and 105 are removed and onelarge roll of paper substituted, and all the pasting and folding devicesare dispensed with, and the cuttingknife R and delivery-apron arrangedas shown in Figs. 15 and 16 for the wrappers.

For cutting the endless band of paper longitudinally two rollers, 148and 149, are substituted for the feed-rollers 97 98, the lower roll, 118, being provided with narrow circular grooves, into which fit steelcircular cuttingblades on the upper roll, 1 19. The paper passingbetween these rolls is thus cut into longitudinal bands, which aresevered transversely by the knife R, and finally piled onto the apron 7in the manner I have already described with reference to the bags.

In Figs. 17 and 18 I haveillustrated a modification of the constructionof the devices for supporting the rolls of paper, the bands of paper,instead of being simply drawn off the rolls, having a positive feedingmotion imparted to them in accordance with the movement of the operatingparts of the machine. The rolls of paper in this case, instead of beingmounted on axles 104 and 105, rest on drum's16et and 165 and 166 and167, resser-rolls 168 and 169 being arranged to bearon the rolls ofpaper. These drums receive an intermittent motion from a rack on anextension of the longitudinal bar 38 through the medium of the pawl andratchet 150, Fig. 18, and train of gearwheels 151, 152, 153, 151, 155,156, and 157, indicated by dotted lines in Fig. 17. It will be evidentthat the amount of paper fed forward is in exact proportion to thedemand, so that there can be no waste.

In order to arrest the motion of the drums with greater accuracy apivoted brake, 160, Fig. 17, having an arm, 159, acted on by a pin onthe rack, may be applied to the drum 164.

I claim as my invention- 1. The combination of bag-making mechanism witha roll of paper and supporting-drums 164 165, and devices, substantiallyas described, whereby a positive intermittent motion is imparted to saiddrums in accordance with the operation of the moving parts of themachine.

2. The combination of a paste trough, 23, and vibrating paster 29 with abar or strip, 30, adapted to fit loosely in guides in the frame,substantially as described.

3. In a bag-machine, the combination of rolls 109 110 and dies 18 withcheek-pieces and operating cams and knives 17, and bar 19, adjustable insaid cheek-pieces, as set forth.

4. The combination of the grooved pulleys- 33 and bars 35 36, adapted tofit in the grooves of said pulleys, with rotating pastebrushes forapplying paste to the flanges of the pulleys.

.5. The combination of rollers: 55 57 and apron passing round saidrollers with reciprocating jaws L embracing said apron, andoperating-rods K K, connected to said jaws.

6. The combination of the endless apron and rollers with presser-bars 11 45 and reciprocating feeding'jaws embracing said apron, substantiallyas specified.

7. The combination of the endless apron with jaws L, consisting of asliding plate, 52, and plate 52, movable on said plate 52, and carryingaspring-plate, 53.

S. The combination of a sliding plate, 52,

and plate 52 with bars 140 and 14.1 and opcrating-cams for separatingthe plates during their backward motion and closing them on theirforward motion.

9. The combination of the knife R, cuttingedge, presser-bar, andbed-plate with the folder 100.

10. The combination of rolls 5 6 and blade 101 and frame having pivotedarms 120 with inclined planes 23 24 and bars 12 118, provided with stopsor projections, all substantiallyas set forth.

11. The shaft 8, provided with a ratchetwheel operated from some movingpart of the machine, and with the notched wheel 8, in combination withthe piy'oted arm 10, provided with a projection and carrying a pinion,11, adapted to convey motion to the endless band 7 on the depression ofthe arm 10, all substantially as described.

12. The within-described method of making paper bags from two sheets ofpaper, by first pasting the ends of the strips, then partially foldingthe overlapping edges of one strip, pasting theinner faces of thesefolds and folding them over onto the other strip, then severing the tubethus formed, and folding and pasting the closed end, all substantiallyas set forth.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
